While at the local Flea Market this morning, I picked up a small compressor. From the looks of it, it was cobbled together from parts. A Hausfeld-Campbell tank, A Craftsman 1hp Motor, etc.
The gentleman selling it said that the pully on the pump had been broken, and he stuck another on it, but then the motor would "trip the electrical breaker". All I could do at the time was turn the pump over by hand - and it sounded OK. I turned on the electrical motor w/o belt attached, and it seemed OK.
When I got it home, after cleaning the oil and dirt off of it, I hooked up the belt and fired 'er up. As soon as it built up about 10-15 PSI, the back pressure would cause the motor to drag, and the belt would slip. While running it sounding good.
Questions:
1) What should the ratio on the motor to pump pulleys be?
2) How to I set it up so that the motor shuts off at say 125 PSI?
3) Sources for cutoff relays?
4) Should I abandon.
My needs are few in terms of a compressor - occasional Brad Nailer, and cleanup around the shop.
I Paid $50 for it, and figure that the parts are worth that - I can always use a 1HP motor if nothing else.
I will need a regulator - One guy had a nice new one with a moisture trap for a good price, but I was out of cash. When I when back a couple of hours later, he had packed up. May try next week.
Any advice would be appreciated - even if it is to abandon.
Thanks
Mark
